摘 要：车联网通信的信道建模是保障车辆高可靠、低时延通信的关键。本文首先介绍现有典型的车联网信道模型标准；然后对主流的第三代合作伙伴计划(3GPP)车联网信道模型的发展进行简要概述；最后重点介绍3GPP提出的WINNER+B1信道模型，并针对高速和城市两种典型场景下的信道建模进行深入探讨。WINNER+B1信道模型在车联网建模中具有多场景适应性、动态信道参数、高精度路径损耗等优势，能够精确模拟车辆在不同场景下的复杂通信环境。

Abstract: Channel modeling for vehicle-to-everything(V2X)communication is essential to ensure high re-liability and low latency for vehicular networks.This paper begins by introducing existing standard V2Xchannel models,followed by a concise overview of the evolution of the mainstream 3GPP V2X channel model.Finally,it focuses on the WINNER+B1 channel model proposed by 3GPP and provides an in-depth discussion of channel modeling for two typical scenarios:high-speed and urban environments.The core strengths of the WINNER+B1 channel model in telematics applications include its adaptability to multiple scenarios,dynamic channel parameters,and high-precision path loss estimation,which enables accurate simulation of complex vehicular communication environments across diverse settings.
Key words: V2X; channel modeling; high-speed; urban
